Dear Sir/Madam, My name is Diogo Lopes Dias de Moraes, and I am a postgraduate student in Criminal Sciences at the Catholic University of Salvador in Brazil. I am currently writing my final paper (TCC) on the admissibility of blockchain hash registration as atypical evidence for the digital chain of custody in the Brazilian criminal justice system. Estonia is globally recognized as a leader in e-governance and the use of distributed ledger technology. For my research, it would be invaluable to understand how your country's legal and technical systems handle this matter. Could you please provide any information or public documentation regarding the official procedures or standards used in Estonia for establishing and maintaining the chain of custody for digital evidence, specifically through the use of blockchain technology or the X-Road system? Any guidance on this topic, or being directed to the appropriate department or expert, would be of great assistance to my academic work. Thank you for your time and consideration. Sincerely, Diogo Lopes Dias de Moraes Postgraduate Student, Criminal Sciences Catholic University of Salvador Salvador, Bahia, Brazil
